To commemorate Pokémon Day on February 27, Pokémon GO developer Niantic has teamed up with The Pokémon Company International for its annual celebration of all things Pokémon. From February 26 at 1 p.m. PST to March 6 at 1 p.m. PST, special Pikachu appearing all over the world will be celebrating Pokémon Day by wearing festive party hats. These special Pikachu will keep their party hats forever, but they can only be found during this limited-time celebration, so be sure to keep an eye out for them as you explore. Don’t forget to use the Pokémon GO AR Camera to take pictures of the special Pikachu you encounter and share them on social media using #PokemonDay.
